2〕采用串行接口與主處理器進(jìn)行通信，接口信號(hào)線數(shù)量大幅度減少，包括電源和地在內(nèi)的信號(hào)線僅有9條。支持多種串行通信協(xié)議〔如AVR單片機(jī)的ＳＰI、MCS51的串口模式０等〕，傳輸速率高達(dá)4Mbps，可全速寫入顯示數(shù)據(jù)，無(wú)等待時(shí)間。

3〕可通過(guò)導(dǎo)電膠連接模塊與印制版，而不用連接電纜，用模塊上的金屬鉤可將模塊固定到印制板上，因而非常便于安裝和更換。

4〕LCD控制器／驅(qū)動(dòng)器芯片已綁定到LCD晶片上，模塊的體積很小。

5〕采用低電壓供電，工作電壓為3,3V，正常顯示時(shí)的工作電流在200μA以下，且具有掉電模式。
